Assume that the distribution coefficient for compound X between chloroform and water is 2.8. If 50 mL of water that is initially 0.1 M in X is extracted with three 25-mL portions of chloroform:
a) What if the final concentration of X remaining in the aqueous phase?
b) How many millimoles of X remain in the aqueous phase?
c) If X has a MW of 156, how many grams remain in the aqueous phase?
d) If instead of using 25-mL portions of chloroform, one 75-mL portion has been used, how much of the solute would remain in the aqueous phase?
e) What can you conclude about the desirability of using one large portion or several small portions of solvent for extractions?

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
